From springs to flows
Discover how i-spring is setting a new standard in flow analysis
The story of i-spring Systems AG began at Federnfabrik Schmid AG, where the technology was originally developed to measure the tiniest deformations in spring assemblies – a high-precision system for real-time condition monitoring.
During the development phase, however, a key insight emerged: the same measurement principle could also be applied to pipelines. Instead of a spring, the pipe wall itself becomes the sensor – and instead of force, the system now measures internal pressure.
Everything happening inside the pipe becomes visible because every pressure change produces minute deformations, which i-spring precisely detects and analyses.
The principle is similar to our own bodies: blood vessels respond to pressure fluctuations, and sensors in the vessel walls send feedback to the brain, which adjusts the heartbeat accordingly.
In the same way, i-spring feels what is happening inside the pipeline – delivering real-time data on flow velocity, direction, behaviour, and anomalies.
Key Advantages:
• non-intrusive, media-free measurement – hygienic, safe, and easy to retrofit
• reliable with challenging media – works with foams, emulsions, highly viscous or non-Newtonian fluids
• beyond measurement – early detection of leaks, deposits, and flow disturbances
• smart connectivity – wireless communication and IoT integration for Industry 4.0

With i-spring, what was once considered a “disturbance signal” – pressure pulsation – becomes a valuable source of information, enabling greater efficiency, process quality, and operational safety.
